Fresh water antifreeze??

Thread Rating

Go on Peaks website and read the label for the antifreeze. I think it is ok to drink, but I wouldn't make it a habit. The residual left over in water lines is probably fine, but a cup full probably would loosen the pipes. I have tasted it and it is foul. Kind of oily and sweet.
 
you don't want to be drinking that stuff....you put it in your lines to protect them over the winter. I took me 4 tanks of water and baking soda, flushing thru to get rid of the taste finally. It's got a mint type, mostly antifreeze taste...yuk!!

I just blow out my lines now, then the water doesn't taste bad. If you blow out your lines, then you can use the water periodically over the winter campouts, drain it when you come home, blow it out....Camping world has a little adapter that hooks to your city water connection and you open up your lines and blow it out with a compressor.

RV antifreeze is propylene glycol, and is used to winterize RV and camping vehicle water systems, first draining down all the fresh water as possible, and then RV antifreeze ia pumped through the waterlines to flush out water.
Also its used to winterize a building in winter, such as an unheated cabin. Put in sink traps, toilet traps, etc.

It is considered "non-toxic" thats why its used in this application, but I don't know what drinking a quantity of it would do.
Maybe call a poison control center in your state and ask.

To use the system with water again, usually what people do is fill the freshwater tank in the RV with water, and about 1-cup of chlorine bleach mixed in. and flush out the RV antifreeze.

I have a motorhome and a unheated guest cabin, so I have been through this process many times.

Automotive antifreeze is Ethylene Glycol, and is poisonous to humans and animals.
Hope this helps some.

Yammadog can type faster than me!:D

His technique is another that works too. The RV stuff can leave an after taste when the systen is restored to water, and not flushed through enough.

I tried the compressed air on my motorhome and always ended up with damage to the toilet foot pedal controlled flush valve. Might just be a quirk with the plumbing in my rig. That valve replacement is a hateful job in those older Thetford toilets.

X2. The only thing I put the antifreeze in are the P-traps. I just use the auto stuff.
